I have a Crossbreed super tuck holster I carry my Glock 22 in, great holster. I bought one of the new nylon aliens gear holsters with the plastic clips for another gun I wanted to carry, One day walking around Wal-Mart with the Alien holster on. I could feel the holster working off the belt and creeping up. I went too the rest room and re secured the holster. I placed an order for the metal clips. I have had no further problems with the holster with the Metal belt clips. I know I will not trust the plastic clips again.
